Summary

In order to examine the influence of the geometry of the joint on the strength of ceramic joints, the interface element was proposed as one of the simple models which represent the mechanism of failure in an explicit manner. It was applied to the analysis of the fracture strength of SiC/SiC composite specimen joined by ARCJoinTTM, and the effect of the scarf angle on the joint strength was studied by changing the scarf angle between the composite and the joint. It was clearly shown that the joint strength was governed both by the surface energy and the bonding strength. Moreover, it was found that the strength was affected by the order of the singularity in stress field. Thus, the proposed method was considered to have a great potential as a tool to study the failure problems of various structures.
